关于本原料
Mulberry leaf (Morus alba) — a Kampo herbal raw material with FFC notifications referencing post-meal blood-sugar moderation, anchored in the leaf's deoxynojirimycin (DNJ) content. Japanese cultivation, historically tied to the silk industry, has been re-purposed for kuwa-cha (mulberry-leaf tea) and DNJ-standardised supplement extracts. Nagano (the historic silk region), Gunma, and Kumamoto produce commercial supply; small-volume specialty producers in mountainous Tōhoku also contribute. Distinct from the existing mushroom and bamboo-leaf functional entries.
